A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is
no plug at all. When the plug is pushed down over two pins, the jumper is referred to as jumpered. In some
documents, the jumper setting may be shown in text as two numbers, such as 1-2. The number 1 is printed
on the circuit board so that you can identify each pin number based on the location of pin 1.
Figure 6 shows the location and default settings of the jumper blocks on your system board. See
the designations, default settings, and functions of your system's jumpers.
